Cannot use the extension without paying

Абсолютно не работает в бесплатной версии. Зачем обманывать людей! Зря только время потерял на установку на Arch Linux и на расширение.

Aucune possibilité de connexion sans abonnement payant alors que l'app Android / Mac/Windows propose des serveurs gratuits .

This is my first addon review ever.

I give it 1 star, because at the current time it has no use for me. It's paid. You get nothing free. I suggest to make it at least 10 minutes/ 1 hours a day free vpn.

If you add free stuff, I will edit my review

Open source and all that nonsense just as an excuse to get email addresses?

Lures you with free use (See Website with the big Button "Proton Free"), although it is only for payment, which you only find out afterwards when you have already registered your email address.
Privacy and honesty look different.
